feat: refactor case detail from useState tabs to URL-based nested routes
Refactors the monolithic cases/[id]/page.tsx into Next.js nested routes with a shared layout for the case header and tab navigation bar. Route structure: - cases/[id]/layout.tsx — case header + tab bar (active tab from URL) - cases/[id]/page.tsx — redirects to ./verlauf - cases/[id]/verlauf/page.tsx — timeline tab - cases/[id]/fristen/page.tsx — deadlines tab - cases/[id]/dokumente/page.tsx — documents tab (with upload) - cases/[id]/parteien/page.tsx — parties tab - cases/[id]/notizen/page.tsx — notes tab (new, uses NotesList) New shared components: - Breadcrumb.tsx — reusable breadcrumb navigation - NotesList.tsx — reusable notes CRUD (inline create/edit/delete) - Note type added to types.ts Benefits: deep linking, browser back/forward, bookmarkable tabs.
